Marine fish, or saltwater fish, are more dazzling than most species. They come straight from the ocean. These fish brighten any saltwater aquarium, and go well with many living rocks, anemones, and other invertebrates. Reefs2Go has received much praise for our outstanding selection of the gorgeous exotic fish. When we visit our top customers and view their completed aquariums, we are amazed every time. These fish are just so darn pretty!
Why Are Exotic Fish So Colorful?
Well, we don't know for sure, but scientists are sure working hard trying to figure that out, and we have some interesting explanations from their research. There may be a variety of situation-specific reasons that your tropical aquarium fish have such vibrant colors, because each species of fish has its own unique visual processing (Unlike land animals. Our eyes typically work in generally the same way as other land animals).
One reason that they are so colorful may be that each species of exotic fish may only be able to see one color that happens to be on its own body. That individual fish can signal to others in the same school that a predator may be approaching, or that food is nearby, by showing that particular color without other fish or predators being able to see.
Predators are mostly colorblind, so they can't see the bright colors either way.
The most interesting part about it is that scientists are just scratching the surface with being able to tell the true color of an object; not with our eyes, but with tools. Powerful color-testing tools are used to determine a number rating that puts the object in a color category, because what we humans see with our eyes may be different than what other animals see with theirs. For example, one such exotic fish was found to be a mixture of ultra-violet and yellow, not quite yellow and not quite ultra-violet. With our human eyes, this looked like an orange-ish color. Before this, scientists didn't even know this color existed!
